如何在Spring集成中回滚从 IBM MQ 获取的消息

Question

我有一个Spring集成流程，如下所示：

    1) message-driven-channel-adapter -> 
                 1.1) output-channel connected to -> service-activator -> outbound-channel-adapter (for sending response)
                 1.2) error-channel connected to -> exception-type-router 
                            1.2.1) message is sent to different queues depending on the exception type using outbound-channel-adapter

我已经在消息驱动的通道适配器中设置了 acknowledge=“transactioned”。我想在错误通道之后为特定类型的异常引入回滚。

首先，我尝试将异常类型路由器输出连接到服务激活器。但是我得到了例外:

   Code: 

     <service-activator id="rollBackActivator" input-channel="RollBackChannel" 
             ref="errorTransformer" method="rollBackMessage"/>

     public void rollBackMessage(MessagingException  message){       
         TransactionAspectSupport.currentTransactionStatus().setRollbackOnly();
     System.out.println("Message rolled back:"+TransactionAspectSupport.currentTransactionStatus().isRollbackOnly());
 }

   Exception:
   org.springframework.messaging.MessageHandlingException: org.springframework.transaction.NoTransactionException: No transaction aspect-managed TransactionStatus in scope

然后，我尝试使用出站通道适配器表达式，但是再次得到另一个异常

Code:
<outbound-channel-adapter id="rollbackOut" channel="RollBackChannel" 
     expression="T(org.springframework.transaction.interceptor.TransactionAspectSupport).currentTransactionStatus().setRollbackOnly()"/>

 Exception:
 org.springframework.messaging.MessageHandlingException: Expression evaluation failed: T(org.springframework.transaction.interceptor.TransactionAspectSupport).currentTransactionStatus().setRollbackOnly()

请建议在这种情况下实施回滚。

默认情况下，容器使用会话上的本地事务。不涉及 AOP。只需抛出异常，容器就会回滚消息。
